Erase your iPhone and Start Fresh
A true fresh start wipes old caches, odd glitches, and years of settings. This is a big step, so make sure to back up your iPhone first. When you restore from that backup, you keep your photos, messages, and app data, yet you still get the smooth feel that comes from a new iPhone.
First, make a backup:
- Open the Settings app, tap your Apple Account (Apple ID), and then tap iCloud.
- Scroll down and select iCloud Backup.
- Tap Back Up Now and wait until it completes.
When your backup is finished and you’re ready to start over with a clean slate, go to Settings, tap General, then scroll down and go to Transfer or Reset iPhone. Tap Erase All Content and Settings and follow the instructions on your screen.
Once that is done, your iPhone will delete everything so you can start fresh. Choose to download your recent backup, or just start using your iPhone like it’s completely new.
